These rodents were sampled from pellets Received in revised form collected in Europe from 381N (Portugal) to 651N (Finland) with most samples coming from sites 25 September 2012 18 located in France and Spain. Large oxygen isotopic variability in d Op is observed both at the intra- and Accepted 28 September 2012 inter-species scale within pellets from a given location.
